Which graph represents a function?​

Answer:

Step-by-step explanation:

Area = 72 m^2

L = 12m

Formula

w = Area / L

Perimeter = 2L + 2W

Solution

72m^2 = 12 W      Divide both sides by 12

72/12 = 12W / 12

W = 6 m

Perimeter = 2L + 2W

Perimeter = 2*12 + 2*6

Perimeter = 24 + 12

Perimeter = 36 m

Answer:

2

Step-by-step explanation:

2 is the rate of change for the graph because y/x=2 I am not sure wich unit of rate is larger because I cant see the equation

The proportionality constant will be equal to 2.

The ratio of two proportional values at a constant value is known as the constant of proportionality. The constant (commonly abbreviated k) related sums that increase or decrease simultaneously. It is the proportion between the values y and x.

Given table is below,

X      Y

2     4

3     6

4     8

5     10

6     12

The proportionality constant will be calculated as,

Y = KX

4 = K x 2

K = 4 / 2

K = 2

Therefore, the proportionality constant will be equal to 2.

Answer:

Slope Intercept form: y = mx + b

Step-by-step explanation:

mx: the slope

b: y- intercept

To find the slope, use this formula:

y₂ - y₁ / x₂ - x₁

Add in the numbers

1 - (-5) / 0 - 2

-6/2 (or -3) = slope

Use point-slope form to find the Y- intercept

y - y₁ = m (x - x₁)

y - (-5) = -3 (x - 2)

y + 5 = -3x + 6

Subtract 5 from both sides

y = -3x + 1 ← Slope intercept form

Graph the y- intercept at 1, and go down 3 and to the right 1. Your two coordinates will be (0 , 1) and (1, -2) .

Explicación: Solo puede factorizar, o simplificar, una ecuación o solo variables, si la variable que tiene un exponente tiene la misma base que otra variable, como x ^ 2 y x ^ 3, puede simplificarla ax ^ 5. Ahora, en este problema tenemos un 3, y 2 ^ 2, en el 2 ^ 2, 2 es la base y el otro número es 3, que definitivamente no es la misma base, por lo que no puede factorizarlo más, y deje la variable a lo largo.

Answer:

[tex]y=-\frac{3}{2}x+12[/tex]

Step-by-step explanation:

Hi there!

We want to write the equation of a line parallel to y=[tex]-\frac{3}{2}x-1[/tex] and that passes through the point (4,6)

Parallel lines have the same slopes, but different y intercepts.

The slope of the equation [tex]y=-\frac{3}{2}x-1[/tex] is [tex]-\frac{3}{2}[/tex], since the equation is written in y=mx+b format (m is slope and b is y intercept), and [tex]-\frac{3}{2}[/tex] is in the place where m is.

It's also the slope of the line parallel to it.

So we know the slope of the new line, let's write it down:

y=[tex]-\frac{3}{2}x[/tex]+b

Let's find b, in order to complete the equation

Since the equation passes through the point (4, 6), we can use it to solve for b.

Substitute 4 as x and 6 as y into the equation:

6=[tex]-\frac{3}{2}[/tex](4)+b

Multiply

6=-6+b

Add 6 to both sides

12=b

Substitute 12 as b in the equation.

y=[tex]-\frac{3}{2}x+12[/tex]

I did synthetic division on the righthand side to make sure the answer was correct. Hope this helps :)

Answer:

[tex]\displaystyle x - 10[/tex]

Step-by-step explanation:

Since the divisor is in the form of [tex]\displaystyle x - c,[/tex]use what is called Synthetic Division. Remember, in this formula, -c gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so do not forget it. Anyway, here is how it is done:

−1| 1 −9 10

↓ −1 10

________

1 −10 0 [tex]\displaystyle \hookrightarrow x - 10[/tex]

You start by placing the c in the top left corner, then list all the coefficients of your dividend [x² - 9x - 10]. You bring down the original term closest to c then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder. Finally, your quotient is one degree less than your dividend, so that 1 in your quotient will be an [tex]\displaystyle x,[/tex]then you end it off with [tex]\displaystyle 10,[/tex]giving you the quotient of [tex]\displaystyle x - 10.[/tex]

The maximum area of the pen is the highest area the pen can have

The maximum area is 16200 square yards

Let the dimension be x and y.

So, the perimeter is given as:

[tex]\mathbf{P = 360}[/tex]

Because it has one additional fence, the perimeter is calculated as:

[tex]\mathbf{2x + y = 360}[/tex]

Make y the subject

[tex]\mathbf{y = 360 - 2x}[/tex]

The area is calculated as:

[tex]\mathbf{A = xy}[/tex]

Substitute [tex]\mathbf{y = 360 - 2x}[/tex]

[tex]\mathbf{A = x(360 -2x)}[/tex]

Expand

[tex]\mathbf{A = 360x -2x^2}[/tex]

Differentiate

[tex]\mathbf{A' = 360 -4x}[/tex]

Set to 0

[tex]\mathbf{360 -4x = 0}[/tex]

Rewrite as:

[tex]\mathbf{4x = 360}[/tex]

Divide both sides by 4

[tex]\mathbf{x = 90}[/tex]

Substitute 90 for x in [tex]\mathbf{A = 360x -2x^2}[/tex]

[tex]\mathbf{A = 360 \times 90 - 2 \times 90^2}[/tex]

[tex]\mathbf{A = 16200}[/tex]

Hence, the maximum area is 16200 square yards

Answer: 11

Step-by-step explanation:

This is a problem of solving word problems using systems of equations.

Let's denote 2-seat tables by x and 4-seat tables by y. Therefore, their sum will be the total number of tables, which is 28. So, x + y = 28.

Now, let's concentrate on the number of customers. It says that 'when all tables are full, there will be 90 customers in the restaurant'. Therefore if we seat 2 people on each 2-seat table(x), their total number will be 2x and if we seat 4 people on each 4-seat number(y), their total number will be 4y. Hence, 2x + 3y = 90.

Now, we have a system with two equations:

[tex]\left \{ {{x + y = 28} \atop {2x + 4y = 90}} \right.[/tex]

Multiply the first line by -4.

[tex]\left \{ {{-4x -4y = -112} \atop {2x + 4y = 90}} \right.[/tex]

Now, by adding up these two equations, we get the following:

-2x = -22

x = 11

This means that the restaurant has 11 two-seat tables.
